Families are vastly overlooked in US initiatives to promote population health and health equity despite being the most proximal context for health across the life course. We urge the public health sector to take the lead in recognizing families as essential for promoting 21st century population health. We highlight ways families influence health by providing context, care, continuity, and connections.

Stressors and trauma experienced by persons fleeing harm or persecution can cause elevated distress. This study assessed predictors of elevated distress among newly arrived refugees, asylees, and Special Immigrant Visa (SIV) holders in Maryland. A secondary analysis of Refugee Health Screener-15 data from 4385 refugees, asylees, and SIV holders arriving in Maryland from 2014 to 2017 was conducted.

Objectives: To investigate prenatal, perinatal, and early childhood factors, including cord and early childhood plasma leptin, on a clinical diagnosis of obstructive sleep apnea (OSA) among children in the Boston Birth Cohort.

Study Design: We conducted a secondary analysis of 2867 mother-child pairs from the Boston Birth Cohort who were enrolled between 1998 and 2014 at Boston Medical Center and followed from birth to age 16 years. Child's OSA was defined based on clinical diagnoses documented in the medical record.

Article Synopsis
  • Postpartum visits (PPVs) are important for new mothers to receive health counseling, but many in Maryland don't attend these appointments due to various risk factors.
  • A study analyzed data from 2012-2013 showing that 89.6% of mothers attended PPVs, with significant factors affecting non-attendance including being unmarried, experiencing infant loss, working during pregnancy, and not receiving dental care.
  • The findings underline the need for targeted support, especially for mothers who've lost an infant, to improve attendance and overall postpartum care.

This study examines transitions in grandchild care and the characteristics of grandparents making these transitions, using longitudinal data from a nationally representative sample of 13,626 grandparents in the 1998-2008 Health and Retirement Study. More than 60% of grandparents provided grandchild care over the 10-year period; more than 70% of those did it for 2 years or more. Grandparents with fewer functional limitations and more economic resources were more likely to start or continue nonresidential care, whereas relatively disadvantaged grandparents were more likely to start and continue coresidential care.

We quantify the base dependent interactions between single stranded DNA and single walled carbon nanotubes (SWNTs) in solution. DNA/SWNT hybrids hold the promise of applications ranging from nanoscale electronics and assembly of nanotube based materials, to drug delivery and DNA sequencing. These applications require control over the hybrid assembly and disassembly.

This article develops a series of hypotheses about the long-term effects of one's history of marriage, divorce, and widowhood on health, and it tests those hypotheses using data from the Health and Retirement Study. We examine four dimensions of health at mid-life: chronic conditions, mobility limitations, self-rated health, and depressive symptoms. We find that the experience of marital disruption damages health, with the effects still evident years later; among the currently married, those who have ever been divorced show worse health on all dimensions.

Objective: The objective of this study was to test a conceptual model of loneliness in which social structural factors are posited to operate through proximal factors to influence perceptions of relationship quality and loneliness.

Methods: We used a population-based sample of 225 White, Black, and Hispanic men and women aged 50 through 68 from the Chicago Health, Aging, and Social Relations Study to examine the extent to which associations between sociodemographic factors and loneliness were explained by socioeconomic status, physical health, social roles, stress exposure, and, ultimately, by network size and subjective relationship quality.

Result: Education and income were negatively associated with loneliness and explained racial/ethnic differences in loneliness.

Most studies of social relationships in later life focus on the amount of social contact, not on individuals' perceptions of social isolation. However, loneliness is likely to be an important aspect of aging. A major limiting factor in studying loneliness has been the lack of a measure suitable for large-scale social surveys.

Eleven female drug-court participants looked at current and past experiences to assess their program and envision future program innovations. From these women's perspective, the strongest component of drug court was being surrounded by staff dedicated to their progress and recovery. Graduated supervision and accurate drug testing were appreciated rather than resented when the participants were not humiliated and were treated with respect.

We measured the UV optical absorption of single-stranded DNA bound to single-walled carbon nanotubes (DNA/SWNT). The nucleotide absorbance from DNA/SWNT provides the first experimental confirmation that DNA binds to nanotubes through pi-stacking. Because the hypochromic absorbance typical of pi-stacked structures are expected to occur primarily for DNA dipole transitions that lie along the axis of the optically anisotropic SWNTs, the absorbance changes following binding of DNA to nanotubes reveal the preferred orientation assumed by each of the four bound nucleotides with respect to the nanotube's long axis.

Objectives: The purpose of this study was to examine the effects of caring for grandchildren on health behaviors and mental and physical health among older adults.

Methods: Using a sample of 12,872 grandparents aged 50 through 80 from the Health and Retirement Study, we examined the relationship between stability and change in various types of grandchild care and subsequent health, controlling for covariates and earlier health.

Results: We found no evidence to suggest that caring for grandchildren has dramatic and widespread negative effects on grandparents' health and health behavior.

The extent to which loneliness is a unique risk factor for depressive symptoms was determined in 2 population-based studies of middle-aged to older adults, and the possible causal influences between loneliness and depressive symptoms were examined longitudinally in the 2nd study. In Study 1, a nationally representative sample of persons aged 54 and older completed a telephone interview as part of a study of health and aging. Higher levels of loneliness were associated with more depressive symptoms, net of the effects of age, gender, ethnicity, education, income, marital status, social support, and perceived stress.

Elasmobranchs (sharks, skates, and rays) possess an electrosensory system with an infrastructure of canals connecting the electrosensors to the environment. The electrosensors and canals are filled with a uniform hydrogel, but the gel's function has not yet been determined. We present electrical admittance spectra collected from the hydrogel from 0.

We describe a technique for measuring a Seebeck effect in gels and present data for three systems. Notably distinct signals are obtained for gel originating in the electrosensitive organs of marine sharks, synthetic collagen-based gel, and as a control, seawater, the gels' solvent. Only the gel of sharks shows a reversible thermoelectric signal.

To investigate the physical mechanism of the electric sense, we present an initial electrical characterization of the glycoprotein gel that fills the electrosensitive organs of marine elasmobranchs (sharks, skates, and rays). We have collected samples of this gel, postmortem, from three shark species, and removed the majority of dissolved salts in one sample via dialysis. Here we present the results of dc conductivity measurements, low-frequency impedance spectroscopy, and electrophoresis.

People living in some arrangements show better health than persons in other living arrangements. Recent prospective studies document higher mortality among persons living in particular types of households. We extend this research by examining the influence of household structure on health using longitudinal data.
